Discussion on the use of neutralizing water quality rice vinegar

For the northern orchid friends, the water quality is a major problem related to the cultivation of bluegrass. The water quality in the northeast is not well understood, but the water quality in the northwest is generally alkaline and contains more calcium. In the past, some northern orchid friends used rice vinegar to neutralize the water quality. I have also tried this method for a few years, but in the past two years, I have gradually discovered the disadvantages of this method-soil consolidation, affecting air permeability. The reason is that the acetic acid in rice fault and calcium in water form calcium acetate, and calcium acetate is the reason for the long-term application of basin soil consolidation, such as the use of granular plant material, the reflection seems to be slightly better, just a layer of white powder on the surface of the basin soil. However, with the increase in the accumulation of calcium acetate, it is necessary to change the plant material once a year or two. Such as the use of mountain soil and other plant materials, hardening is particularly obvious. Not long ago, I consulted the comrades of the laboratory department of the hospital, and they put forward two schemes: one is to water the flowers with pure water so that PH plants can meet the requirements and have no pollution; the other is to neutralize tap water with low hydrochloric acid to avoid the problem of calcium acetate. Watering flowers with pure water, three or two pots are OK, more than dozens of pots are too expensive, and I am still experimenting with hydrochloric acid. Of course, the best is Rain Water, but there is little rain in the northwest, so this method is not sustainable. The purpose of this post is to throw a brick to attract jade. I hope that orchid friends in the north will discuss together on the water use of orchids. (Tang Liang)
